The issue of running MTH engines on a ZWL comes up now and again - https://ogrforum.com/topic/are...-mth-engine-friendly - but I haven’t read of anyone with my problem.
I recently replaced my ZW Multi Watt with a ZWL. The ZWC (if that’s what it can be called) had been working well in conventional (since I cut the antenna), but I’m ready to think about command control, hence the upgrade. Question is this: I have two MTH locos – a Protosound PRR K-4 (MT-3018LP upgraded to PS3) and a PS-2 GG1 (20-5553-1 upgraded with a PS-32 5V board) - that seemed to be running fine with the ZWC but with the ZWL they run very slow even with the throttle wide open. Barely above a crawl. I am still running everything conventionally. All other locos – Lionel, Atlas with TMCC, Williams and Weaver – run fine.
The output on the ZWL is above 18 volts, but could there be a problem in the ZWL, which is still under warranty?
I know there are issues about waveforms, but aren’t the waveforms of the PH-180 bricks and the ZWL the same? Or maybe the issue of ZWC vs, ZWL is irrelevant. Is the ZWL simply incompatible with certain MTH engines? Should I avoid adding any more MTH locos if I want to keep the ZWL?
Any thoughts would be appreciated. I’d love to hear I am doing something stupid.
